Self Assessment Quiz

1. For electromagnetic wave propagation inside a good conductor, show that the electric and the magnetic fields are out of phase by 450.

2. A  2 kHz electromagnetic propagates in a  non-magnetic medium having a relative permittivity of 20 and a conductivity of 3.85 S/m. Determine if the material is a good conductor or otherwise. Calculate the phase velocity of the wave, the propagation and attenuation constants, the skin depth and the intrinsic impedance.

3. An electromagnetic wave with  its electric field perpendicular  to the plane of incidence is incident from vacuum onto the surface of a perfect conductor at an angle of incidence q. Obtain an expression for the total electric and the magnetic field.
